图4. 生成网络中使用的注意力模块. 根据解码部分特征图dl与其上一层编码部分特征图el-1作为输入，计算注意力系数矩阵α，el-1与注意力系数矩阵α逐像素相乘来选择聚焦区域
Fig. 4. The attention modules used in generator network. The attention coefficient matrix α is calculated by using the decoded partial characteristic graph dl and the coded partial characteristic graph el-1 as the input, el-1 multiplies the attention coefficient matrix α pixel by pixel to select the focus region
